Background: Chronic conditions increase the risk of invasive pneumococcal diseases (IPD). Pneumococcal vaccination remarkably reduced IPD morbimortality in vulnerable populations. In Brazil, pneumococcal vaccines are included in the National Immunization Program (PNI): PCV10 for < 2 years-old, and PPV23 for high risk-patients aged ≥ 2 years and institutionalized ≥ 60 years. PCV13 is available in private clinics and recommended in the PNI for individuals with certain underlying conditions. Methods: A retrospective study was performed using clinical data from all inpatients from five hospitals with IPD from 2016 to 2018 and the corresponding data on serotype and antimicrobial-non-susceptibility of pneumococcus. Vaccine-serotype-coverage was estimated. Patients were classified according to presence of comorbidities: healthy, without comorbidities; at-risk, included immunocompetent persons with specific medical conditions; high-risk, with immunocompromising conditions and others Results: 406 IPD cases were evaluated. Among 324 cases with information on medical conditions, children < 5 years were mostly healthy (55.9%), while presence of comorbidity prevailed in adults ≥ 18 years old (> 82.0%). Presence of ≥1 risk condition was reported in ≥ 34.8% of adults. High-risk conditions were more frequent than at-risk in all age groups. Among high-risk comorbidity (n = 211), cancer (28%), HIV/AIDS (25.7%) and hematological diseases (24.5%) were the most frequent. Among at-risk conditions (n = 89), asthma (16.5%) and diabetes (8.1%) were the most frequent. Among 404 isolates, 42.9% belonged to five serotypes: 19A (14.1%), 3 (8.7%), 6C (7.7%), 4 and 8 (6.2% each); 19A and 6C expressed antimicrobial-non-susceptibility. The vaccine-serotype-coverage was: PCV10, 19.1%, PCV13, 43.8%; PCV15, 47.8%; PCV20, 62.9%; PCV21, 65.8%, and PPV23, 67.3%. Information on hospital outcome was available for 283 patients, of which 28.6% died. Mortality was 54.2% for those with meningitis. Conclusion: Vaccine with expanded valence of serotypes is necessary to offer broad prevention to IPD. The present data contribute to pneumococcal vaccination public health policies for vulnerable patients, mainly those with comorbidity and the elderly.

The majority of coronavirus disease 2019 (COVID-19) have been confirmed in adults, with only a few reported cases in children. In the pediatric population, COVID-19 infection appears to be often unremarkable or associated with mild respiratory symptoms. Little is known about neurologic complications related to COVID-19 in newborns. We present a case of severe encephalitis with cytotoxic brain edema in a newborn with COVID-19.

Background: Following the first reports of the emergence of methicillin-resistant Staphylococcus aureus (MRSA) in the 1970s, several measures to prevent its transmission were introduced in hospitals. However, controversy continues regarding the best approach to prevent and control MRSA, especially in neonatal intensive care units (NICUs). Objective: To report the reduction of colonization and primary central venous catheter–related bloodstream infection (CRBSI) caused by MRSA through surveillance, decolonization, and adoption of best practices in intravenous catheter care. Methods: Quasi-experimental, nonrandomized, before-and-after intervention study conducted in a 70-bed NICU in a private maternity hospital in Brazil. Period studied comprehended between August 2018 and May 2019 (period 1 - preintervention) and June to December 2019 (period II - postintervention). At the end of period 1, several measures were implanted to control and prevent colonization and CRBSI in the unit. The following measures were implemented: incentive to hand hygiene; best practices training on medication preparation and central catheter manipulation; systematic screening of colonized patients with nasal and umbilical swabs; contact precautions for colonized newborn (NB); contact precautions for twins of a colonized NB even when they had a negative swab; decolonization of patients with nasal mupirocin and chlorohexidine (oral preparation) for oral hygiene; concurrent linen change at the end of the patient’s decolonization; decolonization of parents of colonized siblings with chlorohexidine bath and nasal mupirocin; environmental organization; intensification of cleaning and disinfection of equipment and articles; cohort of patients and workers; isolation and precautions compliance audit; professional investigation and decolonization and universal chlorhexidine bath for newborns. Results: In periods I and II, the positivity rates of the collected swabs were 4.14% and 0.75% (P < .0001), respectively, with a peak of positivity of 11.8% in January. Also, 12 episodes of CRBSI were documented in period I (incidence, 2.9%) versus no episode in period 2, with a significant difference in incidence rate between the 2 periods (P = .002). Conclusion: The innovative measures were effective for eradicating the outbreak when instituted together with recognized good practices. In an outbreak scenario is difficult to define the isolated impact of each measure, although, parents’ decolonization to prevent the colonization of other siblings and contact precautions for twins of colonized NB seemed to improve the results.Funding: NoneDisclosures: None

No. of bitstreams: 0 Previous issue date: 2016 Foundation to Fight against Nosocomial Infections Background: There are no data on surgical site infection (SSI) rates stratified by surgical procedures (SPs) in Brazil, and our objective was to report such rates. Methods: From January 2005 to December 2010 we conducted a surveillance study on SSIs in four hospital members of the International Nosocomial Infection Control Consortium (INICC) in four Brazilian cities. We applied the U.S. Centers for Disease Control and Prevention's National Healthcare Safety Network's (CDC-NHSN's) surveillance methods. Surgical procedures were classified into following types following International Classification of Diseases (ICD-9) criteria. Results: We recorded 349 SSIs, associated to 61,863 SPs (0.6%; [CI], 0.5-0.6). SSI rates per type of SP were compared with INICC and CDC-NHSN reports, respectively: 2.9% for cardiac surgery (vs. 5.6%, p=0.001 vs. 1.3%, p=0.001); 0.4% for cesarean section (vs. 0.7%, p=0.001 vs. 1.8%, p=0.001); 5.4% for craniotomy (vs. 4.4% p=0.447 vs. 2.6% p=0.005) and 1.1% for vaginal hysterectomy (vs. 2.0% p=0.102 vs. 0.9% p=0.499.) Conclusions: Our SSI rates were greater in two of the four analyzed types of SPs compared with CDC-NHSN, but similar to most INICC rates. These findings on the epidemiology of SSI in Brazil will enable us to introduce targeted interventions for infection control.

Objective:To describe the epidemiology of healthcare-associated infections (HAIs) among neonates.Design:Prospective surveillance of HAIs was conducted during 2 years. Infections beginning within 48 hours of birth were defined as HAIs of maternal origin. Death occurring during an active episode of HAI was considered related to HAI.Setting:Seven neonatal units located in three Brazilian cities.Patients:All admitted neonates were included and observed until discharge.Results:Twenty-two percent of 4,878 neonates had at least one HAI. The overall incidence density was 24.9 per 1,000 patient-days, and 28.1% of all HAIs were maternally acquired. HAI rates ranged from 12.3% in the group with a birth weight (BW) of more than 2,500 g to 51.9% in the group with a BW of 1,000 g or less. The main HAIs were bloodstream infection (BSI) and pneumonia. Coagulase-negative staphylococci,Enterobacterspecies,Staphylococcus aureus,andKlebsiella pneumoniaewere the main pathogens. Forty percent of all deaths were related to HAI. Central venous catheter (CVC)-associated BSIs per 1,000 CVC-days ranged from 17.3 (BW, 1,501 to 2,500 g; device utilization [DU], 0.11) to 34.9 (BW, ≤ 1,000 g; DU, 34.92). Ventilator-associated pneumonia per 1,000 ventilator-days ranged from 7.0 (BW, ≤ 1,000 g; DU, 0.34) to 9.2 (BW, 1,001 to 1,500 g; DU, 0.14).Conclusions:The high proportion of HAIs of maternal origin highlights perinatal care issues in Brazil and the need to improve the diagnosis of neonatal HAIs. The very low BW group and device-associated infections should be priorities for prevention strategies in this population.

Staphylococcus aureus colonization is a risk factor for endogenous staphylococcal infection in vulnerable neonates. Several studies describe prophylactic measures for adult population, but very few recommendations are establish for neonatal intensive care unit (NICU). After detecting an increase in severe S. aureus infection in the NICU, the present study has the objective to check if a bundle of measures to decrease S aureus colonization in NICU babies have impact in reducing infection.

Background The occurrence of a respiratory syncytial virus (RSV) outbreak in a Neonatal Intensive Care Unit (NICU) is related to unfavorable outcomes, as this infection can lead to respiratory distress and death in premature in infants. Report the successful control of an outbreak that occurred in April 2010 in a NICU. Methods After the index case, of 18 premature infants placed in the same room 10 infants were infected. Of those 10, 6 developed mild to moderate respiratory symptoms, 4 persisted asymptomatic and no death occurred. Contact and respiratory precautions were rapidly initiated, the infants were cohorted in 3 different rooms and palivizumab was administered to all contacts. Results The outbreak was controlled and no new cases were subsequently indentified. Conclusion Standard infection control measures plus palivizumab prophylaxis were efficient in rapid control of the outbreak.

WOS: 000296843100008 PubMed: 21732120 Purpose To evaluate the impact of country socioeconomic status and hospital type on device-associated healthcare-associated infections (DA-HAIs) in neonatal intensive care units (NICUs). Methods Data were collected on DA-HAIs from September 2003 to February 2010 on 13,251 patients in 30 NICUs in 15 countries. DA-HAIs were defined using criteria formulated by the Centers for Disease Control and Prevention. Country socioeconomic status was defined using World Bank criteria. Results Central-line-associated bloodstream infection (CLA-BSI) rates in NICU patients were significantly lower in private than academic hospitals (10.8 vs. 14.3 CLA-BSI per 1,000 catheter-days; p < 0.03), but not different in public and academic hospitals (14.6 vs. 14.3 CLA-BSI per 1,000 catheter-days; p = 0.86). NICU patient CLA-BSI rates were significantly higher in low-income countries than in lower-middle-income countries or upper-middle-income countries [37.0 vs. 11.9 (p < 0.02) vs. 17.6 (p < 0.05) CLA-BSIs per 1,000 catheter-days, respectively]. Ventilator-associated-pneumonia (VAP) rates in NICU patients were significantly higher in academic hospitals than in private or public hospitals [13.2 vs. 2.4 (p < 0.001) vs. 4.9 (p < 0.001) VAPs per 1,000 ventilator days, respectively]. Lower-middle-income countries had significantly higher VAP rates than low-income countries (11.8 vs. 3.8 per 1,000 ventilator-days; p < 0.001), but VAP rates were not different in low-income countries and upper-middle-income countries (3.8 vs. 6.7 per 1,000 ventilator-days; p = 0.57). When examined by hospital type, overall crude mortality for NICU patients without DA-HAIs was significantly higher in academic and public hospitals than in private hospitals (5.8 vs. 12.5%; p < 0.001). In contrast, NICU patient mortality among those with DA-HAIs was not different regardless of hospital type or country socioeconomic level. Conclusions Hospital type and country socioeconomic level influence DA-HAI rates and overall mortality in developing countries.

Hand hygiene (HH) is the most important strategy to reduce healthcare associated infection. Central line associated bloodstream infection (CLABSI) is the most frequent and severe infection in the Neonatal intensive care unit (NICU).

Group B Streptococcus (GBS) is the main etiological agent of neonatal sepsis in developed countries, however there is no detailed information on its incidence in Brazil. We registered the incidence and lethality of GBS infection in a Brazilian private maternity hospital from April 1991 to March 2000. Maternal risk factors contributing to neonatal infections were also scored. The rate of infection was determined by checking for GBS in the blood and liquor of symptomatic neonates within 72 hours of birth. Sepsis and/or early onset meningitis were diagnosed in 43 neonates (32 cases in blood, 1in liquor and 10 in blood and liquor). The overall incidence was 0.39 per thousand neonates and remained quite constant throughout the period, ranging from 0.25-0.63. Septic shock occurred in 33 neonates within 1 to 36 hours of birth (mean 15 hours). Among those patients, 26 (60%) died between the 5th and the 85th hour after birth. Maternal risk factors, according to CDC criteria, included: gestational age below 37 weeks in 26 cases (60%), amniorrhexis equal or superior to 18 hours in 7 cases (16%), and maternal temperature equal or superior to 38(o)C in 4 cases (9%). None of the mothers had received prophylactic antibiotics during labor nor were urine, rectal or vaginal swabs screened for GBS. Although the incidence of GBS infection in the population in this study was lower than that found in developed countries, its rate of mortality was higher. The death rate could be reduced through recognition of the risk factors and prophylactic antibiotics during labor.

In order to evaluate the epidemiology of candidemia in Brazil, we performed a prospective multicenter study conducted in six general hospitals from Sao Paulo and Rio de Janeiro. We enrolled a total of 145 candidemic patients (85 males) with a median age of 32 years. Non-albicans species accounted for 63% of all episodes and the species most frequently causing candidemia were C. albicans (37%), C. parapsilosis (25%), C. tropicalis (24%), C. rugosa (5%), and C. glabrata (4%). Systemic azoles were used before the onset of candidemia in only six patients. There were no differences in the coexisting exposures or underlying diseases associated with the species most frequently causing candidemia. The overall crude mortality rate was 50%. Nosocomial candidemias in our tertiary hospitals are caused predominantly by non-albicans species, which are rarely fluconazole resistant. This predominance of non-albicans species could not be related to the previous use of azoles.

Scabies epidemics are not unusual, and the recommended way of stopping them is by simultaneous treatment of everybody in the facility; this has been known since the last century, when Norwegian scabies was a problem in Norway. When this is not done, scabies epidemics can smolder for months. Scabies should not spread with good infection control measures, but we learned that a good infection control service is not enough. Efforts have to be done to educate everybody in the hospital, including laundry workers, and to improve work conditions.

Candida infections account for 80% of all fungal infections in the hospital environment, including bloodstream, urinary tract and surgical site infections. Bloodstream infections are now a major challenge for tertiary hospitals worldwide due to their high prevalence and mortality rates. The incidence of candidemia in tertiary public hospitals in Brazil is approximately 2.5 cases per 1000 hospital admissions. Due to the importance of this infection, the authors provide a review of the diversity of the genus Candida and its clinical relevance, the therapeutic options and discuss the treatment of major infections caused by Candida. Each topography is discussed with regard to epidemiological, clinical and laboratory diagnostic and therapeutic recommendations based on levels of evidence.

Objective:To analyze possible risk factors for death among patients with nosocomial candidemia. To identify risk factors for death in patients with candidemia, we analyzed demographic, clinical, and microbiological data.Setting:Six tertiary hospitals in Brazil.Patients:A cohort of 145 patients with candidemia.Design:26 possible risk factors for death, including age, underlying disease, signs of deep-seated infection, neutropenia, number of positive blood cultures, removal of a central venous catheter, etiologic agent of the candidemia, susceptibility pattern of the isolate to amphotericin B, and antifungal treatment were evaluated by univariate stepwise logistic regression analysis.Results:Non-albicans species accounted for 63.4% of the candidemias. Risk factors for death in univariate analysis were older age, catheter retention, poor performance status, candidemia due to species other than Candida parapsilosis, hypotension, candidemia due to species other than Candida parapsilosis, and no antifungal treatment. In multivariate analysis, older age and non-removal of a central venous catheter were the only factors associated with an increased risk for death.Conclusions:These data suggest that patients with candidemia and a central venous catheter should have the catheter removed.
